where i can get "selecting an alternate function for STMH7"

[ykn]

I am very new in STM32, earlier i tried it on CubeMX but no use of it.

now i want o start code on register base. like below

like, https://controllerstech.com/how-to-setup-uart-using-registers-in-stm32/

but i am not getting where is alternate function chart ,there i can assigned UART to GPIO.

thanking you

Actually on USART is working with help of CubeMX but i want to do it with help of register ,

so that I can get idea what is happening in Cubemx

The datasheet has the mapping between pins and each AF mode.

 

If you want to use direct register access, also get familiar with the reference manual.
